Really don't understand why are complaining about merit system. Those who want to rank up, still manage to do it. Just take a look on this topic
Because it prohibits them from easily earning here straight away. muenze makes his gripes clear in the very post you quoted:
People with a lot of Merit can earn $50 in BTC a week easily and more in signature campaigns. They have absolutely ZERO motivation to give others Merit because if anything giving others Merit will give them more competition in the signature campaigns.
I somewhere heard a story about a man who entertained people by drawing their portrait with toothpicks and he charged $100 for his work of 5 minutes. Once he was asked why dafuq one should pay this much money for a bunch of toothpicks that he/she would probably throw away after some time. Then the guy said he spent 30 years of his life in order to perfectly own his technique. So it's not about the result that you see at the given time, it's about the amount of effort and investment that one put until he got to the point where he/she is now.
"People with a lot of Merit" did not register their profiles with those "a lot of Merit" inside.
Not exactly true. If you registered before the introduction of the merit system all you needed was the activity which just required you to make one post every fortnight, hence the introduction of the merit system as people were easily farming accounts just by shitposting.
